ABSTRACT The current pandemic has generated many conspiracy theories (CTs). In this paper, we investigate several determinants of COVID-19 CTs using survey data from Romania. Some of our findings are consistent with those of previous studies on other CTs: low values of social integration, open-mindedness, and analytical thinking predict conspiracy thinking as well as higher levels of collective narcissism. Other findings run counter to those of prior research on CTs. We hypothesize that this might be due to the specificity of the CTs under scrutiny and related to the Romanian context.
